So i am doing a valve adjustment. I have done a lot on yfz's but  this is my first on the yz450.

 

I measuered all the clearances and found 2 intake( .08 / .08 / .15) and one exhaust ( .15 / .20) to be slightly out.

I did the proper adjustment and now they are perfect however the 1 intake and 1 exhaust valve that were orginally in spec that i did not touch are now way out. I cant get a gauge in to even check the measurment (it may even be .000)

 

what happened!?

 

now my measurments are EX (.20) (.000) IN (.15) (.15) (.000)
